Dog ear yeast infection
Diseases, parasites, and other conditions of dogs and cats
What is a dog ear infection?
A dog ear infection is a condition in which bacteria are present in the ear canal, the opening of the external auditory meatus of the dog. Bacteria, along with earwax and debris, will make their way into the ear canal and the ear drum of the dog. Ear infections can be easily treatable, but your dog must be treated as soon as possible to prevent the infection from spreading into the internal ear and causing more serious ear infections and damage.
The most common signs of a dog ear infection are a foul-smelling discharge and an obvious swelling of the ear. Dogs with ear infections also may have head shaking or may appear to be scratching at the ear. Dogs with ear infections may also have a pain in the ear, and they may act irritable, nervous, and uncomfortable.
What causes a dog ear infection?
Dogs get ear infections when there is an opening into the ear canal that allows bacteria, along with earwax and debris, to accumulate. Your dog may have ear infections because of:
Sudden changes in environment such as living conditions or traveling to a new home.
Prolonged exposure to moisture in the ear.
Infections caused by fleas and other parasites.
Exposure to the bacteria in a farm environment.
Infections from contact with other animals, including humans.
The ear canal is lined with a mucous membrane, which is the primary defense of the dog’s ear and is normally moist and clean. Bacteria may enter the ear canal through an opening, such as a crack in the ear, or through the external ear canal itself. Once bacteria make their way into the ear canal of the dog, they can multiply and cause inflammation of the ear canal and the surrounding tissues. When the dog scratches its ear and the debris becomes lodged in the ear canal, it can trigger an infection. If a dog has an ear infection for several weeks, then it may be caused by a combination of factors, including:
A prolonged period of exposure to moisture.
A severe ear infection.
How common are dog ear infections?
Dog ear infections are most common in dogs between the ages of six months and five years, but they can occur in younger or older dogs as well. However, it is rare for dogs to get ear infections during the first month of life, so if your dog is younger than one month old and gets an ear infection, it may be because you had a puppy that had ear infections.
Although many dogs suffer from ear infections, it is fairly rare to find a dog that has them frequently. Ear infections can happen for the first time at any time, but they usually start when your dog is between six months and five years old. Ear infections occur more often in female dogs than in male dogs. In a dog that is at least five years old, it is not uncommon for the dog to have ear infections for several months before they occur.
A healthy dog will not have ear infections for more than a few days to a few weeks at a time. If your dog has a very severe ear infection, it can last for several weeks, and may cause the ear to bulge or swell and cause the ear to look swollen.
What causes an ear infection in dogs?
There are several causes of ear infections in dogs. When a dog has an ear infection, it usually means that a buildup of bacteria has occurred in the ear canal.
The most common causes of ear infections in dogs are:
Fleas. Fleas have the ability to pass the bacteria to a dog through their bite. Ear mites also cause ear infections in dogs.
Fungi. Ear infections from fungi can be caused by allergies to plants or fungi.
Fleas. A flea bite will cause ear infections if the flea has passed the bacteria into the dog’s ear.
Infections from parasites. Ear infections from worms, fleas, and other parasites can infect the dog’s ears.
Ear mites. Ear mites can infest a dog’s ear and cause ear infections. Ear mites live in the ear canal, so they cause an ear infection by passing the bacteria into the ear.
What causes an ear infection in cats?
Cats do not have the same sensitivity to ear infections as dogs, because they do not scratch their ears. Cats do not get ear infections as often as dogs, but ear infections do occur in cats. Ear infections in cats are more common if the cat is exposed to too much moisture, or if there is excessive ear hair, which acts as a breeding ground for bacteria. Ear infections may occur when cats have ear mites. Ear infections in cats are usually not painful.
If you notice any changes in your cat’s ear, contact your veterinarian. The veterinarian can examine your cat’s ears and look for any symptoms that may indicate an ear infection. If your cat has ear infections, your veterinarian can prescribe medicine and/or treat the condition with surgery.
What causes a dog ear infection?
There are many causes of dog ear infections. It is important to know the symptoms of ear infections so that you can act quickly to take your dog to the veterinarian. If your dog has an ear infection, it is important to call your veterinarian as soon as you notice any of the following signs.
A foul-smelling discharge from your dog’s ear.
Swelling or a redness around the dog’s ear.
Shaking of the head.
The dog seems to be uncomfortable.
What does an ear infection look like?
A dog’s ear infection is most noticeable as a discharge from the ear canal. This discharge may be thick and mucous-like, or thin and clear. Sometimes the discharge will have a foul odor.
If the discharge is yellow or greenish in color, this may mean that
